Fennel Seed Foeniculum vulgare
Toast it and crack it, don't powder it. Whole seeds give pockets of sweet anise; a fine grind gives an even dullness.

In the kitchen
Toast then crack
A minute in a dry pan until the smell turns nutty, then a coarse crush in a mortar. Coarse beats fine — you want distinct pockets of anise rather than an even background.
It is a sausage spice
Fennel seed is what makes Italian sausage taste Italian, and it runs through porchetta, finocchiona salami and a great deal of Tuscan pork cookery. With fat and pork it is close to unimprovable.
Bloom it in oil
Whole seeds into hot oil at the start, until they sizzle and darken a shade. Standard in Indian tempering, in Italian sofrito for pork, and in any dish where you want the anise in the fat rather than on top.
Beyond the kitchen
MUKHWAS
Sugar-coated and plain fennel seeds are served after meals across India as mukhwas, a mouth freshener. The bowl by the till in an Indian restaurant is this, and the practice is centuries old.
ABSINTHE AND PASTIS
Fennel is one of the three core botanicals of absinthe with anise and wormwood, and appears in pastis, ouzo, sambuca and a long list of anise liqueurs around the Mediterranean.
MARATHON
The Greek word for fennel is marathon, and the Battle of Marathon was fought on a plain named for the fennel growing there. The race takes its name, at one remove, from this plant.
AN AGGRESSIVE COLONISER
Wild fennel has naturalised across California, Australia and much of the temperate world and is classed as an invasive weed in several. Roadside fennel in California is this plant, growing unchecked.
A longer history
Foeniculum vulgare is native to the Mediterranean and has been cultivated since antiquity. It appears in Egyptian, Greek and Roman records, in Charlemagne's Capitulare de villis, and throughout medieval European herbals and kitchen garden lists — one of the genuinely continuous European culinary plants.
Its uses split early and stayed split. Mediterranean cooking took the bulb and the seed into savoury food; South Asian cooking took the seed into tempering, spice blends and post-meal mukhwas; and European distilling took it into the anise spirits that run from Marseille to Athens.
Seed production today is dominated by India, with Egypt, China and parts of the Mediterranean also significant. Fennel pollen, collected from the flower heads, emerged as a high-value speciality product from Tuscany in recent decades and now commands prices closer to saffron than to seed.
